2 Safety instructions and

recommendations

2.1 Safety instructions

DANGER

If smoke is released or in case of refrigerant leak:

1. Do not use a naked flame, do not smoke, do not

operate electrical contacts or switches ( doorbell,

light, motor, lift, etc..).

Contact between refrigerant and a flame may result

in emissions of toxic gases.

2. Open the windows.

3. Trace possible leaks and seal them immediately.

WARNING

Before any work, switch off the mains supply to the

appliance.

WARNING

Do not touch the refrigeration connection pipes with your

bare hands while the appliance is running. Danger of

burns or frost injury.

2.2 Recommendations

WARNING

4Any intervention on the appliance and heating

equipment must be carried out by a qualified

engineer.

4For a proper operating of the boiler, follow carefully

the instructions.

2. Safety instructions and recommendations AWHP MIT-IN iSystem

924/09/2012 - 300027606-001-01

Keep this document close to the place where the boiler is

installed.

CAUTION

4Use tools and pipe components especially designed

for use with R410A refrigerant.

4Install the appliance on a solid, stable structure able

to bear its weight.

4Use phosphorous-deoxidised copper for pipes

without welds and copper alloy to connect the pipes

carrying the refrigerant.

4Use only R410A gas to fill the pipes with refrigerant.

4Do not install the appliance in a place where it may

be exposed to steam, sulphuric gas or combustion,

an atmosphere with a high salt content, or which may

be covered by snow.

4Ensure correct earthing.

4Store the refrigeration connection pipes away from

dust and humidity (danger of damage to the

compressor) and cover both ends until the expansion

process is complete.

4Do not use a load cylinder.

CAUTION

4Activate the main switch at least 12 hours before the

appliance starts to function. Using the appliance just

after it is switched on may seriously damage the

internal parts.

4When switching off the appliance, wait for at least 5

minutes of post-operation before deactivating the

main switch. Danger of breakdown or water leak.

CAUTION

In order to limit the risk of being scalded, the installation of

a thermostatic mixing valve on the domestic hot water flow

piping is compulsory.

Before carrying out any maintenance work requiring the

shutdown of the inside module, also cut the power supply

to the outside module to prevent any errors in

communication.

24/09/2012 - 300027606-001-01 10

3 Technical description

3.1 General description

The AWHP MIT-IN iSystem heat pump is composed of two

elements:

4The outside unit handles energy production in hot or cold mode.

4The inside module handles thermal exchange between the R410A

fluid and the hydraulic circuit.

The two units are connected by means of refrigeration and electrical

connections.

The system offers the following advantages:

4The heating circuit is housed in the insulated volume within the

home. There is no danger of the pipes freezing.

4Thanks to the DC inverter system, the heat pump modulates its

output to adapt to the needs of the home.

4The control panel uses the outside temperature sensor to adjust

the temperature of the heating circuit according to the outside

temperature.

3.3 Operating principle

3.3.1. General

The outside module produces heat or cold (in reversible versions) and

transmits it to the heating circuit via the refrigerant in the plate

exchanger.

The outside module is capable of operating at outside temperatures

down to -20°C (-15°C in the case of a 6MR or 8MR heat pump).

The DIEMATIC iSystem control panel is used to programme and

regulate the heat pump according to the outside temperature.

By activating the pumps and, where necessary, the mixer valve, the

regulator handles the regulation of the heating.

Connection of a CDR4 simplified remote control or a CDI4 interactive

remote control enables the auto-adaptivity of the gradient and the

parallel offset of the heating curve.

The antifreeze function on the installation is active whatever the

operating mode. It is triggered as soon as the outdoor temperature

reaches the limiting value preset to +3°C.

The installation of a buffer tank is not necessary if the volume of water

in the circuit is higher than or equal to 3 litres/kW: Therefore, for a

heat pump with an output of less than 11 kW, with a water volume of

less than 33 litres, the installation of a buffer tank is necessary.
